The SIMM 100 also includes a user control panel 144. The control panel 144 includes circuitry that is electrically connected with each of the motors 124 and 126. The SIMM 100 receives electrical power from an external power source and the control panel 144 allows a user to use the electrical power to operate the motors 124 and 126 and thereby rotate the wheels 114, 116, 118, and 120. The control panel 144 can also include user-operable controls for selecting one or more of the wheels 114, 116, 118, and 120 to operate, for selecting a rotational direction of the wheels 114, 116, 118, and 120, and for adjusting the speed of rotation of the wheels 114, 116, 118, and 120. The control panel 144 can also include one or more user-operable controls for turning the lights 142 on and off.

FIGS. 9 and 10 show perspective views of the adjustable tool platform 102 in isolation. It should be appreciated that the adjustable tool platform 102 can be used with the SIMM 100 or in other applications with other apparatus. The adjustable tool platform 102 allows a user to selectively position a tool. When used with the SIMM 100 as shown in FIGS. 1-8, the adjustable tool platform allows a user to selectively position a tool relative to any of the wheels 114, 116, 118, and 120. Unless otherwise noted, components of the adjustable tool platform 102 described herein can be formed of any of a number of different rigid materials, for example materials comprising metal, plastic, composite, acrylic, and/or wood.

The adjustable tool platform 102 can be connected to the base 112 via a base guide rail 150 that is mounted to the front side surface 112 d of the base 112. The base guide rail 150 extends along the front side surface 112 d of the base 112 between the left and right side surfaces of the base 112. The base guide rail 150 has opposing first and second raceways 150 a and 150 b that extend along opposing sides of the rail 150. The adjustable tool platform 102 has a first pair of guide rollers 152 a and 152 b that are engaged with the first raceway 150 a, and a second pair of guide rollers 152 c and 152 d that are engaged with the second raceway 150 b.

The adjustable tool platform 102 includes a tool rest member 154 that serves as a support platform for a tool, such as a surgical instrument, while the tool is being serviced by any of the wheels 114, 116, 118, and 120. The tool rest member 154 has a first tool-receiving surface 156 and a second tool receiving surface 158. The second tool receiving surface 158 is orthogonal to the first tool-receiving surface 156. The first tool-receiving surface 156 can include a groove 157 defined by a recessed portion of the surface 156. The groove 157 can be useful for securing tools to the first tool-receiving surface 156 and for maintaining an alignment of a tool relative to the first tool-receiving surface 156.

The tool rest member 154 can be used in conjunction with a variety of interchangeable instrument-mounting lugs, including the first and second instrument-mounting lugs 170 and 180 shown in FIGS. 11 and 12, respectively, that are configured for being removably mounted to the tool rest member 154. In order to accommodate a variety of instrument-mounting lugs such as lugs 170 and 180, the tool rest member 154 includes a first lug-receiving bore 160 having a smooth interior surface, a second lug-receiving bore 162 having a smooth interior surface, and a thumbscrew 164 having a threaded post that extends through the body of the tool rest member 154. The first and second lug-receiving bores 160 and 162 allow for attachment of a lug having a smooth mounting posts and/or threaded posts that can extend therethrough and can be secured with a nut on the opposite side of the bore 160 or 162. The thumbscrew 164 allows for attachment of a lug having an internally-threaded bore.

FIG. 11 shows a first instrument-mounting lug 170, which serves as a first example of a lug that is vertically adjustable relative to the first tool-receiving surface 156 and is configured to be removably mounted to the tool rest member 154. The first instrument-mounting lug 170 includes a first lug body 172. The first lug body 172 includes a smooth post and/or a thumb screw for securing the first lug body 172 to the tool rest member 154 using the first and second lug-receiving bores 160 and 162. The first lug body 172 also includes a clamp assembly 174. The clamp assembly 174 includes a clamp handle 175, a threaded clamp post 176 that is fixed to the clamp handle 175, and a clamp plate 177 that is attached to the clamp post 176 opposite the clamp handle 175. The threaded clamp post 176 extends through a threaded clamp bore 178 though the first lug body 172. Thus, while the first instrument-mounted lug 170 is attached to the tool rest member 154, when a user rotates the clamp handle 175 in a first direction, the clamp plate 177 will move closer to the first tool-receiving surface 156, and when a user rotates the clamp handle 175 in a second direction (opposite the first direction), the clamp plate 177 will move further from the first tool-receiving surface 156. Preferably the clamp plate 177 is aligned with the groove 157 in the first tool-receiving surface 156 so that a tool having a shaft that is at least partially retained within the groove 157 can be further secured thereto by the clamp assembly 174.

FIG. 12 shows a second instrument-mounting lug 180, which serves as a first example of a lug that is horizontally adjustable relative to the second tool-receiving surface 156 and is configured to be removably mounted to the tool rest member 154. The second instrument-mounting lug 180 includes a second lug body 182. The second lug body 182 includes a smooth post 183 and a threaded bore (not shown) for securing the second lug body 182 to the tool rest member 154 using the first lug-receiving bore 160 and the thumbscrew 164. The second lug body 182 also includes a clamp assembly 184. The clamp assembly 184 includes a clamp handle 185, a threaded clamp post 186 that is fixed to the clamp handle 185, and a clamp plate 187 that is attached to the clamp post 186 opposite the clamp handle 185. The threaded clamp post 186 extends through a threaded clamp bore 188 though the second lug body 182. Thus, while the second instrument-mounted lug 180 is attached to the tool rest member 154, when a user rotates the clamp handle 185 in a first direction, the clamp plate 187 will move closer to the second tool-receiving surface 158, and when a user rotates the clamp handle 185 in a second direction (opposite the first direction), the clamp plate 187 will move further from the second tool-receiving surface 158.

Referring again primarily to FIGS. 9 and 10, the adjustable tool platform 102 further includes a post member 190 for supporting the tool rest member 154. The post member 190 extends between the tool rest member 154 and a first support bracket 192. The post member 190 is also attached to a shaft 194 that extends through the first support bracket 192 and is rigidly fixed to the post member 190. The shaft 194 is rotatable relative to the first support bracket 192 about the longitudinal axis A1 of the post member 190. Rotation of the shaft 194 causes rotation of the post member 190 about the longitudinal axis A1, thereby allowing for rotational adjustment of the tool rest member 154 and any tool supported thereon relative to any of the wheels 114, 116, 118, and 120. The shaft 194 is also configured for receiving a knob 196 that can be mounted thereon such that rotation of the knob 196 causes rotation of the post member 190 about the longitudinal axis A1 of the post member 190. In some embodiments, the knob 196 can include indicia thereon for providing a user with a visual indication of the degree of rotation of the post member 190 relative to the first support bracket 192.

The first support bracket 192 includes a bottom surface 198 and a first plurality of guide rollers 200 a-200 d mounted to the bottom surface 198.

The first support bracket 192 is supported by a first guide rail 202. The first guide rail 202 includes opposing first and second raceways 204 a and 204 b. The first and second guide rollers 200 a and 200 b are engaged with the first raceway 204 a and the third and fourth guide rollers 200 c and 200 d are engaged with the second raceway 204 b such that a user can slide the first support bracket 192 along the first guide rail 202 in the directions indicated by arrow A2 in order to adjust the position of the tool rest member 154 relative to any of the wheels 114, 116, 118, and 120.

The first guide rail 192 is supported by a first guide rail support element 206, which in turn is supported by a second support bracket 208. The second support bracket 208 includes a wall member 210, a first support arm 212, and a second support arm 214. The first and second support arms 212 and 214 are rigidly attached to the wall member 210 and extend from the wall member 210 towards the first guide rail support element 206. The first and second support arms 212 and 214 are pivotally connected to the first guide rail support element 206 such that the first guide rail support element 206 can rotate relative to the second support bracket 208 about the pivot axis A3 in the directions indicated by arrow A4.

The wall member 210 includes a wall surface opposite the first and second support arms 212 and 214. A second plurality of guide rollers 218 a-d are mounted to the wall member 210 on the wall surface opposite the first and second support arms 212 and 214. The wall member 210 also includes a guide bore 220 extending therethrough for receiving a guide post 222 (shown in FIG. 9).

A limiter strap 224 is connected between the second support bracket 208 and the first guide rail 202 for limiting the pivotal range of motion between the second support bracket 208 and the first guide rail 202. The limiter strap 224 can be secured to the wall member 210 and to the first guide rail 202 using commonly known hardware or other connection methods. The limiter strap 224 can be a flexible, elongated element having a predetermined length that does not extend beyond what would allow an undesirable degree of pivotal rotation between the first guide rail 202 and the second support bracket 208. The desirable degree of rotation can be selected based on preferences of the user and can be adjusted by adjusting the length of the limiter strap 224. The limiter strap 224 can be made of any of a variety of known flexible materials, such as flexible metal strapping or nylon string.

The second support bracket 208 is supported by a second guide rail 226. The second guide rail 226 includes opposing third and fourth raceways 228 a and 228 b. The guide rollers 218 a and 218 b are engaged with the third raceway 228 a and the guide rollers 218 c and 218 d are engaged with the fourth raceway 228 b such that a user can slide the second support bracket 208 along the second guide rail 226 in the directions indicated by arrow A5 in order to adjust the position of the tool rest member 154 relative to any of the wheels 114, 116, 118, and 120.

The guide post 222 has a lower end that is connected to the second guide rail 226 via a rigid connection plate 230. The guide post 222 is a rigid post that extends from the connection plate 230 in a direction parallel to the longitudinal axis of the second guide rail 226 and through the guide bore 220 of the wall member 210 of the second support bracket 208. A compression spring 232 extends about the guide post 222 between the lower end of the guide post 222 and the second support bracket 208. The compression spring 232 urges the second support bracket 208 away from the connection plate 230 so that the tool rest member 154 remains generally at an elevation close to that of the wheels 114, 116, 118, and 120 while still being adjustable downward towards the connection plate 230.

The second guide rail 226 is supported by a carriage member 236. The carriage member 236 is rigidly attached to the second guide rail 226 and includes a carriage surface 238 opposite the second guide rail 226. The guide rollers 152 a-d are mounted to the carriage surface 238.

The carriage member 236 is supported by the base guide rail 150. The base guide rail includes opposing raceways 150 a and 150 b. The guide rollers 152 a and 152 b are engaged with the raceway 150 a, and the guide rollers 152 c and 152 d are engaged with the raceway 150 b such that a user can slide the adjustable tool platform 102 along the base guide rail 150 in the directions indicated by arrow A6 in order to adjust the lateral position of the tool rest member 154 relative to any of the wheels 114, 116, 118, and 120.

The SIMM 100 thus provides a servicing platform that allows for servicing a variety of tools, for example surgical instruments, using a variety of servicing wheels and a tool support platform that is highly adjustable for easily positioning a tool relative to a servicing wheel. The SIMM 100 is also a compact system that can be used in a fixed or mobile location. For example, as shown in FIG. 13 a mobile servicing station can be realized by providing the SIMM 100 in a vehicle such as a van. Also, as shown in FIG. 14, a mobile servicing station can similarly be realized by providing the SIMM 100 in a towable trailer. In still further examples, a mobile servicing station can be realized by providing the SIMM 100 on a cart or other such mobile apparatus.
